Definitions

  • the invention relates to a folding sword drive for a folding machine according to the Preamble of protection claim 1.
  • a folding sword drive for a folding machine is known from DE 38 09 449 C1, at which a positively guided folding sword over connecting links with two swivel links is connected back and forth synchronously for driving the folding blade be pivoted. Because of this construction, the speed of the Folded swords have a sinusoidal shape so that the speed is relative slowly changes to a standstill in the lowest reversal point of the folding sword at which the folding sword transfers a sheet of material to folding rollers. Subsequent to the Reversal point the speed increases relatively slowly. This has the consequence that perforated sheets, in particular, are distorted during the transfer to the folding rollers and therefore can be inaccurately folded during further processing within the folding machine.
  • a generic folding sword drive is known from DE-PS 637 535.
  • This folding sword drive has a drive rod guided in the vertical direction, on the a folding sword is attached to the lower end.
  • There is a reciprocating piston on the drive rod attached which is guided in a cylindrical housing. Under the action of a the drive rod is supported on the housing in an upper end position held.
  • the Vacuum chamber of the housing below the piston To move the folding sword into the lower folding position, the Vacuum chamber of the housing below the piston, so that the Piston with drive rod and folding blade moved down.
  • the sheet of material between two folding rollers connects the housing space interrupted below the piston with the vacuum wave, so that the piston moved back to its upper end position due to the spring action.
  • the movement of the felling sword can be in the known folding sword drive by the negative pressure and regulate the spring very imprecisely.
  • the well-known folding sword drive is therefore unsuitable for today's folding machines with a very high clock frequency.
  • the invention has for its object a structurally simple means a folding sword drive to create an exact transfer of a material sheet to the Folding rollers with high cycle times enabled.
  • the lifting drive is operated by a lifting electronic magnet device formed with a magnet armature rod, which is between a first and a second end position is displaceable. If the linear actuator with an electronic Control device is connected, the lifting speed of the Magnetic anchor rod and thus the lifting speed of the drive rod on simple Be exactly adapted to the clock frequency of the folding machine.
  • the drive rod will move in its final position, in which it will bow to the folding rollers passes, suddenly slowed down.
  • the speed of the folding blade is therefore immediate before reaching this end position, so that i.a. also perforated sheets without Delays are passed exactly to the folding rollers.
  • the magnet armature rod preferably stands with one arm around a pivot axis pivotable two-armed lever in connection, the other arm with the Drive rod is connected via a sliding joint.
  • one end of an intermediate link can be articulated on the magnet armature rod the other end of which is articulated on one arm of the lever.
  • the actuator stem is linear. If necessary, the drive rod can also be guided along a curved path.
  • the locking magnet device can be formed by a permanent magnet that holds the magnet armature rod in the de-energized state.
  • an electromagnetic device as a locking magnet device to use, which acts on the drive rod when de-energized and in excited state is out of engagement with the drive rod.
  • the armature rod has a first and a second Stop on in the first or second end position on a first or second Attach the damping element.
  • the noise level can be further reduced in that the drive rod one Has stop that in a transfer end position of the drive rod on a Damping element strikes in which the folding sword a sheet of material on Fold roller pair passes.
  • the folding sword drive shown in FIGS. 1a and 1b has a sword housing 10, in a drive rod 12 is guided vertically by means of bushings 14, 16. At the bottom At the end of the drive rod 12, a folding sword 18 is attached, which is above a Folding roller gap is arranged between two folding rollers 20, 22.
  • a stop collar 24 is screwed onto the upper end of the drive rod 12 in the lower transfer end position of the drive rod 12 shown in FIG. 1b on a Damping disc 26 from Eladur is applied to the upper, from the sword housing 10 protruding end of the upper socket 16 is plugged on.
  • a lifting electromagnet device 32 attached with a cylindrical housing 34 so that the Center axis of the cylindrical housing 34 perpendicular to the center axis of the drive rod 12 runs.
  • a left or right coil (not shown) is arranged within the housing 34.
  • a magnet armature rod 36 extends along the central axis of the housing 34.
  • a stop nut 38 and a lock nut 40 screwed on On the 1a and 1b left end of the magnet armature rod 36 is a stop nut 38 and a lock nut 40 screwed on.
  • Another stop nut 42 is on the extending into the sword housing 10 Section of the magnet armature rod 36 is screwed on.
  • a Swivel bracket 44 attached to which an intermediate link 45 with one end is pivotally mounted.
  • the other end of the intermediate link 45 is with one Lever arm 46 of a two-armed lever 48 articulated.
  • the other lever arm 50 of the two-armed lever 48 extends perpendicular to the one lever arm 46.
  • the two-armed lever 48 is pivotally mounted in the housing 10 about an axis of rotation, which passes through the intersection of the two lever arms 46, 50.
  • the free end of the second lever arm 50 is designed as a fork 51 into which the ball bearing 30 Drive rod 12 engages.
  • a further lifting electromagnet device is located on the right-hand end side of the housing 10 in FIG. 1a 52 provided, the magnet armature rod 54 in a recess 55 in the Drive rod 12 engages when the lifting electromagnetic device 52 in de-energized state and the drive rod 12 in its upper end position (Fig. 1a) located. This causes the folding blade 18 to fall in the de-energized state prevented.
  • the inside of the lifting electromagnet device 52 provided compression spring (not shown) a pressure on the magnet armature rod 54 in Exercised towards the drive rod 12.
  • the magnet armature rod is in the excited state 54 moved in the opposite direction by a spool (not shown) so that the Magnet armature rod 54 out of engagement with recess 55 in drive rod 12 is coming.
  • Damping disks 56 and 58 made of Eladur are on both end faces of the housing 34 attached to which the respective stop nut 38 or 42 in the corresponding End position of the magnetic anchor rod 36 strikes. This reduces the noise level and increases the life of the magnet armature rod 36.
  • FIG. 3 The arrangement of the lifting drive 32 in Fig. 1a, 1b is shown schematically in Fig. 3, the intermediate link 45, the armature rod 36 with one arm 46 of the connects two-armed lever 48, is not shown for reasons of clarity.
  • the housing 34 is the lifting electromagnetic device 32 permanently stored.
  • FIG. 4 differs from the embodiment of FIG. 3 in that the housing 34 of the lifting electromagnetic device 32 at one end is pivotally mounted.
  • the end of the armature rod 36 can be direct be articulated with one arm 46 of the two-armed lever 48. On Intermediate joint is not necessary.
  • the two coils in the housing 34 are thus excited via a central one Control that a transfer of the sheet between the folding rollers 20, 22 to exact Points in time.
